Patented July 14, 1931 UNITED .STATES PATENT OFFICE STEPHEN W. IBRANER, F CHICAGO, ILLINOIS, ASSIGNOR TO VICTOR MANUFACTURING 65 GASKET CO., A CORPORATION OF ILLINOIS GASKET I Application led October 15, 1928. Serial No. 312,534.

This invention relates to improvements in gaskets and particularly to self-cooling gaskets adapted for use on internal combustion en ines.

t is an object of the invention to forma gasket with means for carrying off the heat, which heat in prior structures caused the gasket to burn out or leak, and in time utterly destroyed the usefulness of the gasket, es-

l0 pecially those gaskets used between the cylinder block and head and those used between the exhaust ports and manifolds of an internal combustion engine. Of course, gaskets of this construction are adapted for use on l5 other parts of an engine, but the principal value of the gasket is on parts where intense heat is generated.

An object of the invention is to form gas kets, of usual types, such as those having outer and inner layers of metallic material and refractory material therebetween, with the edges of the gasket so arranged as to provide a coolin space.

Another o ject of the invention is to form means on the gasket to extend beyond the parts with which it is to contact to carry off excessive heat.

Another object of the invention is to form I a gasket of this kind with means provided at the edges arranged to carry ofthe heat,

and so formed as togive an increased amount of surface, as for instance by corrugating the edges.

' Itis also an object of the invention to form a gasket of this kind with means for holding the various layers against displacement, and

the openings therein in alignment with each other.

With these and other objects in view, preferred embodiments of the invention are il lustrated in the accompanying drawings, in which:

Figure 1 is a fragmental plan view of a cylinder head gasket, embodying the features of my invention.

Figure 2 is a section taken along line 2-2 of Fig. 1.

Figure 3 is a modified form of the gasket shown in Fig. 1.

Figure 4 is still another modified form of the gasket shown in Fig. 1.

Figure 5 is a form of exhaust port gasket.

Figure 6 is a sectional view taken on line 6-6 of Fig. 5.

Figure 7 is a fragmental end view of the gasket shown in Figures 1, 3, and 4.

The embodiment of cylinder head gasket shown in Fig. 1 includes preferably top and bottom metallic layers 8 and 9 respectively, made of sheet copper, or the like, and has a resilient filler of flexible refractory material, such as asbestos 11. This lgasket is in all respects a typical cylinder head gasket for use on an internal combustion engine, and is provided with the usual openings 12 substantially the size of the bore of'the cylinders upon which it is to be used. Other openings 13, to accommodate the water jacket openings, as well as openings 14 to fit over the cylinder head bolts are provided.

The metallic layers 8 and 9 and the resilient layer 11 are preferablyheld against displacement by a plurality of reinforcing members 15 disposed respectively in the openings 12, and having external annular flanges 16 engaging the external faces of the gasket around the openings 12. The resilient filler 11 stops short of the edge of the gasket to provide a cooling space between the externalmargins of the layers 8l and 9, and these margins, as here illustrated, are corrugated to provide a substantial cooling surface. The perimeter of the resilient member is substantially the same as that of the cylinder block and head to register therewith, while the layers 8 and 9 are large enough to extend beyond the resilient member and cylinder head and block to Contact with the air and thus effect the cooling of the gasket.

However, in some instances Where desired 9 the exible la er may stop short of the cylinder block so t at the outer edges of the outer layers will ali n with the outside of thecylinder block, t us -forming' a asket that is flush with the outer edges o the cylinder block and still provides a cooling space.

The form of gasket shown in Fig. 3 is in all respects similar to that shown in Fig. 1, excepting that the cooling ed e is only provided between the marglna'l olt holes.

The gasket illustrated in Fig. 4 is simply another form of that shown in Fig. 1, adapted for -use upon the manifold, especially the exhaust manifold where heat is usuall intense.

T e form of gasket illustrated in Figures 5 and 6 is especiall adapted for use upon an exhaust manifold, ut this construction may also be used on a cylinder head gasket or gaskets adapted for use on other places on the engine, and includes outer la ers 17 and 18 and a plurality of resilient ayers 19, provided with a spacer layer 21 preferabl of metallic material. The layers may be eld together againstV displacement in any approved manner, and as here shown a reinforcing member 22 is secured around the circumference of the opening 23 and has parallel horizontal external annular flanges enga 'ng the layers 17 and 18.

he princi al advantage of this gasket is that it provi es means for cooling the asket,

thereby. increasing its efficiency and lie.

The construction of the gasketis not intended to be limited to the precise embodiments disclosed,'but numerous other embodiments are contemplated within the scope of the claims.
